IMPROVEMENT lN SASH-FASTENINGS.

To all whom it may concern:

Beit known that I, H. NAYLOR, of Pekin, in the county of Tazewell andState of Illinois,

have invented a new and Improved Friction Window Spring and Fastener;and I do hereby -declare that the following is a full, clear, and

thereto. Fig. 2'is a vertical section taken on the plane of the line mfr, Fig. l.

Similar letters of reference indicate like parts.

My invention consists in the employment of a catch and springconstructed and arranged in i uch manner that when the window-sash isclosed the catch will catch and lock either the lower or upper sash, or,when it is desired to raise or lower the sashes, will bear against thestil' of the window with sufficient force to prevent the sash descendingof its own grav ity, 3s will be presently described.

A designates the frame ot' a window, and B B' the lower and upper sash,respectively.

To the frame of the window a piece, a, is secured, to whose end there ispivoted the catch C in such manner that it will have a motion to andfrom the stile 0r side strip-of the window-sash. The said catch carrieson its end a head, b, which will, in the caseof the lower sash, which isclosed, spring over lSpecilcation forming part of Letters Patent No.56,786. dated July 31, 1866.

the top of the said sash, as shown in Fig. 2, so as to hold or lock thesame against its being opened from the outside, and the case of theupper will sink into a recess, lL, so as to hold that sash against itsbeing opened from the outside.

The catch for the upper sash may be arranged as' that shown for thelower sash, if desired.

Between the catch C and the piece a, either a semi-elliptical spring, d,or a spiral or any other suitable kind of spring, is arranged in suchmanner as to continually force the catch toward the stile of thewindow-sash.

It will be observed that thev nose of the catch 0l will bear against thestiles or side strips of the window-frame with sufficient force to holdthe sash at any given distance to which it may be raised or lowered, andthat the sash, when fully closed, will be locked securely without anyother fastening being needed than the catch O.

This device is simple and cheap. lt can be readily applied, and willoperate efficiently for a great length of time.

What I claim as new, and desire to secure H. NAYLoE.
